First, it is essential to ask, “What is the difference between Linux and UNIX?” This is a great Linux question for interviewers because you can test the candidate’s knowledge of two different subjects at the same time. As your interviewee answers, you should look for them to say that UNIX is the operating system that Linux is based on. In addition, they may point out that Linux is free and open source. Primarily, it is community developed, whereas UNIX was developed by larger tech companies. Your prospective Linux developers may bring up the advantages of Linux as well. For example, it usually has more user interfaces, programming options, and fewer viruses.
This week we’ve been selling more things on eBay and return to the office. We round up news from the Ubuntu community and discuss our picks from the wider tech news.
It’s Season 14 Episode 21 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Martin Wimpress are connected and speaking to your brain.
Today we are looking at MX Linux 21 Beta 1. It comes with Linux Kernel 5.10, XFCE 4.16, and uses about 1GB of ram when idling.
In this video, we are looking at MX Linux 21 Beta 1.
It is important for Linux users to be comfortable using a terminal-based text editor like GNU Nano or Vim, because sometimes you are going to have to edit configuration files without being in a graphical environment. But which terminal text editor is the right one for you?
Tom visited the LearnLinuxTV studio recently to present Jay with an awesome gift - a 3D Printed Raspberry Pi Rack that he and his crew built! In this video, we'll talk a bit about the build and give you our thoughts.
In this video, I am going to show an overview of Haiku R1 Beta 3 and some of the applications pre-installed.
My go to launcher is dmenu but if you want something a little prettier but you're not a fan of configuring rofi, ulauncher might be the app for you, plus it comes with a very established plugin community.
Those having to deal with data stored on NTFS partitions from Linux have been eagerly awaiting the "NTFS3" kernel driver that Paragon Software has been working now for a year to upstream into the Linux kernel. No pull request has been sent in yet but the twenty-seventh spin of this driver was published today.
We are pleased to announce that the System Boot and Security Microconference has been accepted into the 2021 Linux Plumbers Conference. This microconference brings together those that are interested in the firmware, bootloaders, system boot and security. The events around last year’s BootHole showed how crucial platform initialization is for the overall system security. Those events may have showed the shortcomings in the current boot process, but they have also tightened the cooperation between various companies and organizations. Now is the time to use this opportunity to discuss the lessons learned and what can be done to improve in the future. Other cooperation discussions are also welcomed like those based on legal and organizational issues which may hinder working together.
This year, the ELC will take place in Seatle but will be organised as a hybrid virtual/physical event due to the pandemic. As usual the ELC will have a really interesting schedule with 46 talks covering a wide range of topics: build system, kernel graphics, boot process, security, etc.
Audacity audio editor and recorder 3.0.3 was released a few days ago. Finally it adds official Linux binary via Appimage.
Audacity 3.0.3 comes with minor bug-fixes, and binary changes. For Windows users, now it provides 64-bit EXE and 32-bit plug-ins will not work on the release.
The release introduced automatic app update checking. According to the updated Privacy Notice, Audacity needs a network connection for update checking. And this shares your IP address, OS, and Audacity version. You can disable the feature in the Preferences.
Flatpak is the next-generation of packing applications and games for Linux and now you can directly support it.
The idea behind Flatpak is that anything packaged up with it will work across multiple distributions, with a stable environment for everything thanks to common libraries to link against and developers can add any dependencies they need right into the package to ensure it works everywhere. Sandboxing is another prominent feature and one of the main goals of Flatpak packages, to increase security by isolating applications from each other with sandboxing and giving limited access to your operating system.
I’ve been looking for a decent “Now Playing” widget for my Ubuntu desktop for a while now, having been inspired by some Rainmeter setups I saw in a thread on Windows desktops.
And I finally found one — but it took some searching.
Now, I appreciate that the days of showing your currently playing track on your actual desktop is are gone. It’s 2021, and most Linux desktop environments (including GNOME, which Ubuntu uses) support MPRIS controls in some form or another.
Standalone now playing ‘widgets’ (like the much-missed CoverGloobus, pictured as part of a particularly impressive desktop below) are few and far between.
Yooka-Laylee is a platformer game developed by Team 7, which was the original developer team behind the N64 game Banjo-Kazooie. Here’s how to play this game on your Linux PC.
Rocky Linux has emerged as one of the top contenders to replace CentOS for many businesses. And for most, that server-centric Linux distribution will be deployed mostly on bare metal or as a virtual machine. But there's another route to take, one that should have container developers quite pleased.
The developers of Rocky Linux have released a container image, so you can start developing your containers based on the new Linux distribution from the originator of CentOS itself. The benefits of this include having a powerful, secure distribution for which to base your containers. And because this is an official release, you can be sure it's been vetted and is safe to use.
Mirror’s Edge is an action/platformer game for PC, Xbox 360, and PS3. It was developed by DICE and published by Electronic Arts. It is set in a futuristic city and follows Faith Connors, an underground parkour courier. Here’s how to play it on Linux.
Today we are looking at how to install Funkin' VS Impostor on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
This tutorial explains how to disable login on Linux both when connecting through ssh.
After reading this tutorial, you will know how to disable ssh password login enabling key authentication instead, increasing your system security. If you are looking for a way to disable the root login only, check this tutorial instead.
“Hypertext markup language” is the basic language of designing a website. Html is known to be a front-end language to design the interface of a website. There are many functions regarding this language. The commands used for designing are known as tags. These tags combine to develop a website. A single HTML code file is responsible for a static website that is not running. Html contents are text, image, shapes, color, alignment, etc. Alignment is an important ingredient in designing as it determines the respective content to handle at a specific place. We will discuss some basic examples in this guide.
The good thing about Linux is that you can easily view and manage everything, from the boot process to the installation of software packages. Here we discuss how you can use the lsof command in Linux to view open files and the processes using them. Knowing how to view this can help you understand how the system works and even take the necessary actions for specific processes.
GIF also knows as Graphics Interchange Format; it has become very popular among social media users in absolutely no time since its introduction. Reason behind the popularity is its low size compared to images and videos. GIF posts attracted more users on popular social media platforms like Facebook, Google Plus, WhatsApp, and Twitter than any other image or video posts.
Many of you might have thought, how one can make a GIF on Linux and its distribution like Ubuntu? So, today I’m going to show you just that. We’re going to have a look at several ways to make animated GIF in Ubuntu. So, without making further delay, let’s get started.
Anybody who wants to get started with Ethical hacking or wants to advance their skills in penetration testing will need a platform to practice whatever they learn using the various security tools available.
Performing penetration tests on systems without administrative permission is considered illegal and can land you in huge problems, including a jail term with hefty fines. Practice makes perfect, but then, where do you practice hacking skills?
There are so many platforms available that you can use to practice penetration testing. Some of these are online platforms like TryHackMe, HackTheBox, etc.
By reading this tutorial, you’ll learn how to check if a package is installed on Debian-based Linux distributions, including Ubuntu.
In this tutorial, we will show you how to install OneDrive on Ubuntu 20.04 LTS. For those of you who didn’t know, Microsoft’s OneDrive is one of the most popular cloud storage service platforms offered by Microsoft, similar to Dropbox, Google Drive. In the software market and it is an obvious choice for companies and customers who frequently use Microsoft Office programs like Excel and Word. We will learn some of the benefits here.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Microsoft OneDrive on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
AppImage is a software distribution format for Linux that aims to solve two of the most pressing issues with traditional Linux packages: distribution and installation.
If you've downloaded a program in the AppImage format and are wondering how to install or run it on your system, this guide will help you out.
Follow along as we delve into AppImage, its advantages over traditional Linux packages, and the steps you need to follow to run an AppImage file on your Linux machine.
Knowledge on logging with Docker can be very helpful for day-to-day system administration activities, be it troubleshooting or basic monitoring. Without tracking logs on Docker, mitigating issues would be a lot more difficult when investigating anomalies.
This write-up explores some important information on that area to make it easier to understand how to manage Docker associated log files on your Linux system.
Let me start by exploring the most basic parts and gradually go deeper into some specifics.
Total War Saga: Troy won’t be ported to Linux, with the potential native version of the game having been officially canned by Feral Interactive – and doubt being cast on further conversions to Linux.
Feral is well-known for porting big-name games across to Linux, but with Troy it’s only doing a Mac version to follow the release of the strategy game on Steam (following its exclusivity period with Epic expiring).
Spindle certainly has an interesting premise that's worth keeping an eye on. You take on the role of Death, as you try to find out why no one seems to able to die, with your pet Pig companion.
"Spindle is an old-school zeldaesque action-adventure where you slip into the role of Death. But you won't be alone: A loyal companion, a friend who will stay at your side even through the darkest of times, a mate you can always rely on will always follow you: The pig. Your little shiny pink buddy. In fact, the pig is more than that. It will help you on your mission, to restore the natural order."
We mentioned recently that the newly announced Open 3D Engine (O3DE) from the Linux Foundation and Amazon AWS was closer to proper Linux support, and we have a fresh update on that.
The initial pull request from developer Fabio Anderegg on hooking up Linux support for the Editor has now been closed, as a bunch of work towards it has low landed upstream into the main project - which is great progress. Anderegg mentioned on Twitter yesterday (July 28) that the O3DE development branch builds and runs on Linux with a tiny patch!
Here we go again, ahead of the weekend a fresh version of Proton Experimental has gone live allowing you to test the latest adjustments for playing Windows games on Linux. If you're not clear on what Proton and Steam Play are, be sure to check out our constantly updated dedicated page.
We are closely following the renewed explosion of the Kiss-Linux project. Read their latest news stories in their new site kisslinux.org so we don’t paraphrase what has been done. No more Xorg, still faithful to the promise of no-elogind, clean wayland, seatd, sway, etc.
Glaucus, Sabotage, Mere Linux continuing their development. Don’t forget them because of problems normal on Alpha-Beta transitions.
Obarun: Still undermined by gossip from Arch and other rivals who just piece other developers’ software together to provide a distro having none of their own, in disbelief that 66 provides what it states it provides, and the common easy critic of the unknown by those who fail to comprehend. Without systemd (and its off-spring elogind) Obarun remains the sole solution for an every day working linux system.
Void: Apart from mobinmob’s work in his own (repository=https://codeberg.org/mobinmob/void-66/raw/branch/master) to compliment the induction of S6/66 into the repositories, and the many contributions of the Trident Project the development is just rolling along as expected. It is still possible with some maneuvering to run a wm without elogind, dbus, and other pests. Still no sign of development of a new package manager, the old xbps developer left, replaced licenses and left it as it was. As far as we had last seen there was no further change. No urgency I suppose.
Linux, the kernel is growing and growing. At what rate, if you haven’t noticed, appears a little alarming. Some very stable distros lark behind, 5.7 or earlier. But arch (and void) follow the latest stable kernels. See what the size differential is in Arch while replacing 5.13 with the latest of 5.7 (not too long ago):
The latest iteration from the Solus developers is out with kernel 5.13 and plenty of new features, bug fixes, and new hardware support.
Solus is the Linux distribution dedicated to the Budgie desktop. And this time around Budgie has received plenty of bug fixes and updates that add up to a much-improved performance and reliability. Those changes to the desktop environment also include new themes, window customizations, improved notifications, screen tracking, and more.
But the big additions come by way of the Linux 5.13 kernel. By shipping with this new kernel, Solus introduces support for Apple’s M1 chipset, Intel’s Alder Lake S Graphics, AMD’s FreeSync/Adaptive-Sync, and a generic USB display driver. These additions mean Solus can run on even more hardware and will benefit from the performance gains offered by those chipsets and features.
Sharing and using data sets has never been a smooth job. Data set distributors usually must write extensive documentation about their data sets that data consumers must go through. This documentation is often error-prone, and an inadvertent error can cause significant confusion. On the other hand, data consumers must spend a significant amount of time understanding the structure of the data archive and write complicated code to extract and load them.
We are pleased to announce that Red Hat Satellite 6.9.4 is generally available as of July 29, 2021.
Red Hat Satellite is part of the Red Hat Smart Management subscription that makes it easier for enterprises to manage patching, provisioning, and subscription management of Red Hat Enterprise Linux infrastructure.
Red Hat and Nutanix have joined forces to enable a powerful solution for building, scaling and managing cloud-native applications on-premises and in hybrid clouds. The collaboration brings together technologies, enabling installation, interoperability and management of Red Hat OpenShift and Red Hat Enterprise Linux with Nutanix Cloud Platform, including Nutanix AOS and AHV.
The system defaults to a dual-core, 1.3GHz Atom x5-E3930 running Linux or Win 10 IoT. You can load up to 8GB DDR3L-1866 RAM via a single socket.
There are many ways to run Android apps on desktop computers. Desktop emulators like BlueStacks are popular, you could run Android x86 in a virtual machine (or dual-boot it), or you could wait for Windows 11’s Android app compatibility layer. Anbox is another solution for running Android apps, intended to support Linux and Linux-based smartphones, but it suffers from slow performance on low-power devices. Now there’s another project that aims to bring Android apps to Linux devices, but without the slowdowns and jank commonly found with Anbox.
WayDroid (via Linux Smartphones), formerly called Anbox-Halium, is a rebuilt version of Anbox that is designed to use more of the host device’s native hardware than Anbox — which means faster performance. The project’s main focus is running Android apps on Halium-based Linux phones (Halium is similar in concept to Android’s GSI, but for standard Linux), but it can also run on any devices with a mainline Linux kernel.
It’s been a hell of a year so far for data privacy. Apple has been launching broadsides at the ad-tech industry with each new big privacy feature unveiling. Google is playing catch-up, promising that Android users will also soon be able to stop apps from tracking them across the internet. Then there’s WhatsApp, going on a global PR offensive after changes to its privacy policy elicited consumer backlash.
There’s no doubt about it, digital privacy is shaping up as the key tech battleground in 2021 and the years ahead. But how did this happen? Wasn’t digital privacy supposed to be dead and buried by now? After all, many tech CEOs and commentators have told us that a zero-privacy world was inevitable and that everyone should just get used to it. Until recently, it would have been tough to argue that they were wrong.
Over the last 18 months, events have conspired to accelerate this shift in public attitudes towards privacy from a niche concern to something much more fundamental and mainstream. In the process, more people also began to see how privacy and security are inextricably linked.
There are multiple ways to find great add-ons on addons.mozilla.org (AMO). You can browse the content featured on the homepage, use the top navigation to drill down into add-on types and categories, or search for specific add-ons or functionality. Now, we’re adding another layer of classification and opportunities for discovery by bringing back a feature called tags.
We introduced tagging long ago, but ended up discontinuing it because the way we implemented it wasn’t as useful as we thought. Part of the problem was that it was too open-ended, and anyone could tag any add-on however they wanted. This led to spamming, over-tagging, and general inconsistencies that made it hard for users to get helpful results.
Our team is proud to introduce new major pg_timetable v4 with the new documentation, configuration file support, reimplemented logging machinery, job and task timeouts support, new CopyFromFile built-in functionality, and many more!
KD Chart 2.8.0 has been released!
KD Chart is a comprehensive business charting package with many different chart types and a large number of customization options. We are constantly improving the package, and have been doing so for years.
KD Chart 2.8.0 is a very minor release. The most notable change is the removal of Qt 4 support. Additionally, users will receive a notification that the QMake build system will no longer be supported in KD Chart 3.0, to make way for CMake.
Today’s low-code and no-code development platforms enable teams of software developers—and even non-coders—to deliver, support, and extend a wide array of applications. They are used to build mobile apps, deliver customer experiences, streamline workflows, modernize legacy applications, automate data integrations, and support data visualizations, to name the more common uses.
The major selling points of low-code and no-code development tools are that they can be used successfully by lower-skilled, “citizen” developers; that they can produce apps faster than using native SDKs; and that they can produce apps for less money. Many (but not all) of the commercial low-code and no-code systems offset your savings on labor costs with their licensing fees or subscriptions.
Following the recent benchmarks seeing how AMD's new AOCC 3.1 compiler has brought some performance improvements over the prior AOCC 3.0 release that introduced initial Zen 3 optimizations, here are some benchmarks looking at how that latest AMD Optimizing C/C++ Compiler performance compares to the upstream LLVM Clang 12 compiler for which it is based as well as against GCC 11 as the latest GNU compiler release that remains common to Linux systems.
While we have several circumstances and will need to take different actions depending on the situation, we utilize the switch case declaration. When there are several criteria, we will need to run several instructions when they are met. In this instance, we may use a long if..else-if declaration or a switch statement. If we have multiple criteria, the difficulty with long if…else-if is that it will become complicated. The switch case is indeed a neat and effective way to treat such states. A switch statement enables a mutable just to be compared to a set of values for equivalence. Every value is referred to as a situation, so each situation is verified against the mutable that is already being turned on.
An array is a group of data objects of the same kind kept nearby in ram. Inside the C programming, arrays are indeed a derivative type of data that may hold primitive data types like int, char, double, float, etc. It may also hold a group of derivative data types like pointers, structures, and so forth. Whenever you wish to record a student’s grades in six courses, we shouldn’t need to create separate variables for each subject’s grades. Alternatively, we may create an array that could hold the marks for every topic in shared memory regions. We may simply retrieve the items by utilizing the array. To retrieve the array’s members, just a few other lines of the C script are necessary. Let’s take a glance at some instances to see the working of arrays in C language. When writing this tutorial, we have been using the Ubuntu 20.04 operating System to elaborate arrays.
The dynamic array can be created by using a vector in C++. One or more elements can be inserted into or removed from the vector at the run time that increases or decreases the size of the vector. The size or length of the vector can be counted using any loop or the built-in function named size(). These ways of counting the size of the vector have been explained in this tutorial by using different examples.
JetBrains announced the release of PyCharm 2021.2. Features Python 3.10 support, auto-reload for browser HTML preview.
Starting with the new release, users from Asian can enjoy the a fully localized UI in Chinese, Korean, or Japanese. And it’s going to end support for several packages, e.g., mako, buildout, web2py, in next release.
The human can understand the visual more as compared to the text form. That’s why people always suggest drawing the big data graph to understand it in a very easy manner. There are different types of graphs available in the market like bar graphs, histograms, pie charts, etc. These different graphs are used according to the dataset and requirements. For example, if you have a dataset of company performance from the last 10 years, then the bar chart graph will give more information about the company’s growth. So like that, the graph choice depends upon the dataset and requirements.
If you are a data scientist, then sometimes you have to handle the big data. In that big data, you are processing the data, analyzing the data, and then generating the report on that. To generate the report on that, you must need some clear image of the data, and here the graphs come in place.
In this article, we are going to explain how to use the matplotlib bar chat in python.
We can use the categorical data to represent the bar chart in python. The bar chart can be horizontal or vertical, which depends upon your design way. The heights of the bar charts depend upon the data points of the dataset because data points are directly proportionate to the height or length of the bar chart.
The Rust team is happy to announce a new version of Rust, 1.54.0. Rust is a programming language empowering everyone to build reliable and efficient software.
Security updates have been issued by Debian (webkit2gtk), Fedora (ruby and webkit2gtk3), Mageia (aspell and varnish), openSUSE (git), SUSE (ardana-cobbler, cassandra, cassandra-kit, crowbar-core, crowbar-openstack, documentation-suse-openstack-cloud, grafana, kibana, openstack-heat-templates, openstack-monasca-installer, openstack-nova, python-Django, python-elementpath, python-eventlet, python-py, python-pysaml2, python-six, python-xmlschema and git), and Ubuntu (libsndfile, mariadb-10.3, and webkit2gtk).
This post will explain SQL injection, the impact of successful SQL attacks, examples of SQL injection techniques, and how to prevent SQL injection.
There are several applications that you can use to learn SQL injection.
In this particular post, we will use the Damn Vulnerable Web Application (DVWA). It’s a web app developed in PHP and MySQL and intentionally made to be vulnerable.
If you don’t have DVWA installed yet, feel free to check out our post on How to set up DVWA on Kali Linux.
Uptycs Threat Research outline how malicious Linux shell scripts are used to cloak attacks and how defenders can detect and mitigate against them.
Siddartha Sharma and Adhokshaj Mishra
Evasive techniques used by attackers, date back to the earlier days, when base64 and other common encoding schemes were used. Today, attackers are adopting new Linux shell script tactics and techniques to disable firewalls, monitoring agents and modifying access control lists (ACLs).
In previous Uptycs Threat Research posts, we discussed the common utilities in Linux, which are generally used by threat actors in the attack chain. In this report, we highlight those common defense evasion techniques, which are common in malicious Linux shell scripts. And then, we outline how Uptycs spots and mitigates against them.
OpenSSF, a cross-industry collaboration to secure the open source ecosystem, has announced new membership commitments to advance open source security education and best practices. New members include Accurics, Anchore, Bloomberg Finance, Cisco Systems, Codethink, Cybertrust Japan, OpenUK, ShiftLeft, Sonatype and Tidelift.
Earlier this week, we wrote about some of the biggest cases coming up in patent litigation, and the one topping a Law360 list was none other than Fortress Investment-backed VLSI vs. Intel.
Already, the meritless litigation is tying up the too-busy Western District of Texas docket with a series of questionable patent lawsuits between the patent troll and the tech company.
As Patent Progress so aptly puts it: “There’s a reason that more than 85% of cases filed in front of Judge Albright are filed by NPEs.”
It's the same reason that Judge Albright handles more and more of the nation's patent cases (a full 25% of them according to the most recent figures).
From Reuters: The WDTX has “transformed into a hot spot” for patent troll cases under U.S. District Judge Alan Albright.
Given all that, this other bit of news is also concerning.
It centers on VLSI's firm of choice, Irell & Manella.
We all knew that former United States Patent Office Director Andrei Iancu rejoined Irell & Manella after stepping down from the USPTO.
We’ve written about Iancu before and how his changes to the patent system played to the interests of patent troll plaintiffs.
Now, word is that—fresh off of making a ton of money litigating in Western Texas on behalf of VLSI—Irell is expanding its footprint . . . there’s an office coming to D.C. . . . and only Irell knows where it will expand to after that.
Boy howdy.
For all the patent trolls out there, and for firms like Irell, there’s lots of money to be made in Waco.
Only trouble is — it comes at the cost of American jobs and American innovation.
